Referring to FIGS. 17-18 a flowchart of a method for assembling the battery cell carrier assembly 10 will now be explained.

At step 410, the battery cell 44 is disposed on the trapping member 40 such that the trapping member 40 contacts at least a portion of a first side of the battery cell 44. The trapping member 40 has a gasket 42 disposed in the groove 102 of the trapping member 40 that contacts an outer periphery of the battery cell 44. The trapping member 40 has apertures extending therethrough for allowing air to flow therethrough to contact the first side of the battery cell 44 for cooling the battery cell 44.

At step 412, the panel member 46 is disposed on the trapping member 40 to form the battery cell carrier 12 such that the battery cell 44 is held between the panel member 46 and the trapping member 40. Terminals 144, 146 of the battery cell 44 extend through slots 126, 128, respectively, of the trapping member 40. The panel member 46 has apertures extending therethrough for allowing air to contact the battery cell 44 for cooling the battery cell 44.

At step 414, battery cell 244 is disposed on a trapping member 240 such that the trapping member 240 contacts at least a portion of a side of the battery cell 244. The trapping member 240 has the gasket 242 disposed in a groove of the trapping member 240 that contacts an outer periphery of the battery cell 244. The trapping member 240 has apertures extending therethrough for allowing air to flow therethrough to contact a side of the battery cell 244 for cooling the battery cell 244.

At step 416, panel member 246 is disposed on the trapping member 240 to form the battery cell carrier 14 such that the battery cell 244 is held between the panel member 246 and the trapping member 240. Terminals 260, 262 of the battery cell 244 extend through slots of the trapping member 240. The panel member 246 has apertures extending therethrough for allowing air to contact the battery cell 244 for cooling the battery cell 244.

At step 418, the battery cell 284 is disposed on the trapping member 280 such that the trapping member 280 contacts at least a portion of the battery cell 284. The trapping member 280 has a gasket 282 disposed in a groove of the trapping member 280 that contacts an outer periphery of the battery cell 284. The trapping member 280 has apertures extending therethrough for allowing air to flow therethrough to contact the battery cell 284 for cooling the battery cell 284.

At step 420, the panel member 280 is disposed on the trapping member 280 to form the battery cell carrier 16 such that the battery cell 284 is held between the panel member 286 and the trapping member 280. Terminals 290, 292 of the battery cell 284 extend through slots of the trapping member 280. The panel member 286 has apertures extending therethrough for allowing air to contact the battery cell 284 for cooling battery cell 284.

At step 422, of the endcap member 20 is disposed on the trapping member 40 of the battery cell carrier 12.

At step 424, the battery cell carrier 12 is disposed on the panel member 246 of the battery cell carder 14.

At step 426, the battery cell carrier 14 is disposed on the panel member 286 of the battery cell carrier 16.

At step 428, the trapping member 280 of the battery cell carrier 16 is disposed on the endcap member 18.

At step 430, the endcap member 20 is fixedly coupled to the battery cell carrier 12. In one exemplary embodiment, the endcap member 20 is ultrasonically welded to the battery cell carrier 12.

At step 432, the battery cell carrier 12 is fixedly coupled to the battery cell carrier 14. In one exemplary embodiment, the battery cell carrier 12 is ultrasonically welded to the battery cell carrier 14.

At step 434, the battery cell carrier 14 is fixedly coupled to the battery cell carrier 16. In one exemplary embodiment, the battery cell carrier 14 is ultrasonically welded to the battery cell carrier 16.

At step 436, the endcap member 310 is fixedly coupled to the battery cell carrier 16. In one exemplary embodiment, the endcap member 310 is ultrasonically welded to the battery cell carrier 16.

The battery cell carrier assembly 10 can having battery cell carriers 12, 14, 16 represents a substantial advantage over other assemblies. In particular, the battery cell carriers 12, 14, 16 provide a technical effect of holding battery cells therein while providing apertures for allowing air to cool the battery cells. Thus, a temperature of the battery cells can be maintained less than a threshold temperature to prevent the battery cells from being degraded by excess heat.

While the invention has been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiment disclosed for carrying this invention, but that the invention will include all embodiments falling within the scope of the appended claims. Moreover, the use of the terms, first, second, etc. are used to distinguish one element from another. Further, the use of the terms a, an, etc. do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items.
